This then is special permission given by you that is not given by a
straightforward reading of the GPL license.  Imagine that you distribute
your program with GoGui as the main interface.  Is this not a derivative
work?

I wish more people would choose the LGPL over the GPL.  I imagine most
people who write GPL software also get paid to write proprietary
software, so they see the need for both open and closed software.  LGPL
gives the advantages of the GPL (modifications must be redistributed as
source), without the viral nature of the GPL.  I think it is a good
middle ground between BSD and GPL.  It encourages proprietary interests
to contribute back to the open-source world, without trying to take over
their business.

Unless you really believe in Stallman's vision of a GPL world, why not
choose LGPL?
